-WHOO!
-...A TEAM OF ENGINEERS

IS RACING TO BUILD A NEW HOME
FOR THE ATLANTA FALCONS.

MERCEDES-BENZ STADIUM WILL BE
THE WORLD'S MOST ADVANCED

SPORTS STADIUM.

THE SCALE OF THIS
IS JUST GIGANTIC.

Man: LET'S FLOAT THIS.

Narrator: THEY'RE PUSHING TO
COMPLETE THIS AMBITIOUS

GEOMETRIC STRUCTURE IN TIME
FOR THE NEW FOOTBALL SEASON.

TO BUILD THIS COLOSSUS, THE TEAM
MUST BATTLE EXTREME HEIGHTS...

MAN, IT'S AN ADRENALIN RUSH,
BUT AIN'T NOTHING THAT BEATS IT.

Narrator: ...AND DEADLY WINDS.

Martin: IT DON'T MATTER HOW LONG
YOU'VE BEEN DOING THIS,

ONE MISTAKE CAN
COST YOU YOUR LIFE.

Narrator: THIS SUPER STADIUM
RANKS IN A LEAGUE

OF AMBITIOUS NEW
ENGINEERING WONDERS

THAT ARE BIGGER,
FASTER, TALLER,

AND MORE ADVANCED THAN ANYTHING
EVER CONSTRUCTED BEFORE.

ATLANTA, GEORGIA,

THIS SPORTS CAPITAL WITH
HALF-A-MILLION PEOPLE

IS HOME OF
THE 1996 OLYMPIC GAMES

AND 2017 SUPER BOWL FINALISTS,
THE ATLANTA FALCONS.

♪♪

BUT TO ACCOMMODATE ITS GROWLING
NUMBER OF AMERICAN FOOTBALL

AND SOCCER FANS, THE CITY NEEDS
A BRAND-NEW STADIUM.

WHEN COMPLETE, THIS WILL BE ONE
OF THE MOST INNOVATIVE STADIUMS

EVER CONSTRUCTED AND WILL
ECLIPSE THE OLD GEORGIA DOME.

SOARING MORE THAN 300 FEET HIGH
AND COSTING $1.5 BILLION,

THE BRAND-NEW STADIUM WILL BE

THE MOST ADVANCED ARENA
IN THE WORLD.

Hatfield: IT'S SUCH A UNIQUE,
TRULY ONE-OF-A-KIND BUILDING.

THIS IS ONE OF THOSE PROJECTS
THAT HAPPENS ONCE IN A LIFETIME.

Narrator: STRUCTURAL ENGINEER
ERLEEN HATFIELD

HAS HELPED DESIGN THIS
BOUNDARY-PUSHING STADIUM.

Hatfield: WE HAD
A LOT OF CRAZY IDEAS,

AND THAT'S REALLY WHAT ALLOWED
US TO PUSH THE LIMITS

AND COME UP WITH
THIS ICONIC BUILDING.

Narrator: IT WILL TAKE
THREE YEARS FOR AVERY MARTIN

AND HIS TEAM TO BUILD IT.

PART OF THE DANGERS OF
THIS PARTICULAR PROJECT

IS NOTHING IS FORGIVING.

EVERYTHING'S BIG.

EVERYTHING HAS
THE POTENTIAL TO HURT YOU.

Narrator: THIS IS THE GIANT
ERLEEN NEEDS AVERY TO CONSTRUCT.

THIS IS THE VISION.

THE MAIN ENTRANCE REVEALS
THE HEART OF THE NEW STADIUM,

A VAST 270,000-TON CONCRETE BOWL

WILL HOLD 75,000 FANS

AND SUPPORT THE IMMENSE
19,000-TON ROOF STRUCTURE.

FROM THIS HUGE FRAME WILL HANG
THE WORLD'S BIGGEST SCOREBOARD,

A 360-DEGREE, 62,000-SQUARE-FOOT
SCREEN CALLED A HALO BOARD.

IT DESIGNED TO PLAY
IN-GAME ACTION

AND TO BE VIEWABLE FROM
ANY POSITION IN THE STADIUM.

TOPPING IT OFF WILL BE
THE WORLD'S MOST COMPLEX

RETRACTABLE ROOF.

IT WILL BE MADE UP OF
EIGHT VAST, STEEL PETALS

THAT MUST OPEN AND CLOSE
WITHIN 12 MINUTES

TO PREVENT BAD WEATHER
FROM RUINING THE ACTION.

♪♪

DESIGNING AND INSTALLING
THIS ROOF

WILL BE THE MOST CHALLENGING
PART OF THIS AMBITIOUS BUILD.

Hatfield: THIS IS VERY,
VERY COMPLICATED GEOMETRY.

NOTHING LIKE THIS IS EVEN CLOSE
TO HAVING BEEN DONE BEFORE.

MY GOD,
WHAT'D I GET MYSELF INTO?

[ LAUGHS ]

Narrator: BUILDING THIS
ONE-OF-A-KIND ARENA

INVOLVES A SERIES OF KEY STAGES.

FIRST, THE TEAM MUST LAY DOWN
THE 18-ACRE FOUNDATION,

THEN WORKERS WILL BUILD 19 VAST
REINFORCED CONCRETE COLUMNS.

THESE ARE ALL THAT WILL
EVENTUALLY SUPPORT THE ROOF.

THEY MUST ASSEMBLE THOUSANDS
OF PRE-CAST CONCRETE SLABS

TO FORM ITS WALLS AND FLOORS.

THEN THEY MUST TIE
TOGETHER STEEL TRUSSES

TO FORM THE BASE OF THE ROOF.

AND FIT THE DISTINCTIVE
SLIDING PETAL PANELS ON TOP.

INSIDE, THEY MUST
ALSO INSTALL 71,000 SEATS

AND 616 SECTIONS THAT MAKE UP
THE GIANT HALO BOARD.

ONLY THEN WILL THEY DISCOVER IF
THE ROOF PETALS ROLL SMOOTHLY

AND CAN CLOSE TO FORM
A PERFECT SEAL.

WHAT SCARES ME THE MOST,
THAT WHEN WE GO TO PUSH

THE BUTTON ON THE MECHANIZATION,

THAT IT DOESN'T
ALL MOVE PERFECTLY.

Narrator: THE TEAM BEGINS
BUILDING THE 120-FOOT-DEEP

FOUNDATION AND PIECING TOGETHER
THE CONCRETE SLABS

TO FORM THE STADIUM BOWL.

IT TAKES 19 MONTHS TO ASSEMBLE
THE COMPLEX ARENA SHELL.

THEN THEY CONSTRUCT
THE 19 CONCRETE MEGA COLUMNS

AROUND THE PERIMETER
OF THE STADIUM.

Hatfield: THEY'RE GIGANTIC
CONCRETE COLUMNS.

IN A TYPICAL STADIUM, YOU MIGHT
HAVE 50 OR 60 LITTLE COLUMNS

THAT GO ALL THE WAY
AROUND THE PERIMETER,

BUT HERE, WE'RE TRYING TO REDUCE
THE NUMBER OF COLUMNS

TO CREATE A MORE OPEN FEEL,

A BETTER EXPERIENCE
FOR THE SPECTATORS.

Narrator: THE MEGA COLUMNS
WILL SUPPORT

THE 15,000-TON ROOF TRUSSES

THAT ARE BUILT OUT
OVER THE STADIUM BOWL.

Hatfield: THE LONGEST TRUSS
SPANS 720 FEET ACROSS THE BOWL

FROM MEGA COLUMN TO MEGA COLUMN,
SO THEY'RE QUITE BIG.

Narrator: THE ROOF TRUSSES ARE
SO LONG THAT THEY ERECT

THESE TEMPORARY
200-FOOT-HIGH STEEL TOWERS

TO HOLD THEM UP
AS THE TEAM ASSEMBLES THEM

RIGHT OUT ACROSS THE BOWL.

WITH THE TRUSSES IN PLACE,

AVERY NOW FACES
HIS FIRST SIGNIFICANT CHALLENGE.

HE MUST TRANSFER THE WEIGHT
OF THE TRUSSES ON TO THE COLUMNS

SO HE CAN TAKE DOWN
THE TEMPORARY TOWERS.

IT'S GOING TO BE A NIGHTMARE.

Narrator: THIS PROCESS IS CALLED
THE JACK-DOWN.

THE BIG QUESTION IS,
CAN THE COLUMNS TAKE THE WEIGHT?

Martin: IT WOULD BE LIKE
A DOMINO EFFECT.

IF ONE OF THESE COLUMNS
WAS TO BREAK IN HALF,

THEN YOU'D HAVE EVERY ONE
OF THEM FOLLOW SUIT.

IT WOULD BE A CATASTROPHE.

Narrator: SO THIS IS THE PLAN.

AVERY WILL USE HYDRAULIC JACKS

POSITIONED ON TOP
OF THE FOUR TOWERS

TO LOWER THE ROOF TRUSSES DOWN
SLOWLY ON TO THE COLUMNS.

THE JACKS WILL WORK IN UNISON
TO GRADUALLY CLOSE

FOUR MASSIVE STEEL HINGES
AT THE TOP OF EACH TOWER.

THESE HINGES WILL BE
UNDER EXTRAORDINARY PRESSURE.

AS THE HINGES CLOSE, THE WEIGHT
OF THE 15,000-TON TRUSSES

SHOULD SLOWLY SHIFT OFF
THE TEMPORARY TOWERS

AND ON TO THE CONCRETE COLUMNS
AROUND THE RIM OF THE STADIUM.

IF THE WEIGHT
HAS BEEN TRANSFERRED,

THE TEAM SHOULD BE ABLE
TO REMOVE THE TEMPORARY TOWERS

AND CONTINUE TO BUILD.

Martin: THIS IS A BIG,
MAJOR MILESTONE FOR US.

TO GET WHERE WE'RE AT NOW,
IT'S BEEN A LONG, HARD ROAD.

Narrator: TIME IS SHORT.

THE STADIUM MUST BE FINISHED TO
HOST ITS FIRST GAME OF FOOTBALL

JUST NINE MONTHS
FROM THIS POINT.

CAN THEY BUILD IT IN TIME?

Narrator: AT THE NEW HOME
OF THE ATLANTA FALCONS,

ENGINEERS ARE BRACING THEMSELVES

TO LET
THE MERCEDES-BENZ STADIUM'S

15,000-TON TRUSSES STAND ON
THE SURROUNDING COLUMNS

WITHOUT SUPPORT.

THEY MUST LOWER THEM GENTLY,

A PROCESS CALLED
"THE JACK-DOWN."

AND THE STAKES ARE HIGH.

A SUDDEN SHIFT IN WEIGHT COULD
CAUSE THE HINGES TO BUCKLE.

AS WE LOWER THESE HINGES,
EVERYTHING OPENS UP.

SO YOU NEED TO PAY ATTENTION
TO WHERE YOUR BODY IS STANDING.

STAY FOCUSED ON
EVERYTHING YOU'RE DOING.

IT DON'T MATTER HOW LONG
YOU'VE BEEN DOING THIS.

ONE MISTAKE CAN
COST YOU YOUR LIFE.

IF Y'ALL DON'T MIND, LET'S PRAY.

FATHER, WE COME BEFORE YOU
THIS MORNING,

I THANK YOU FOR THIS MILESTONE
THAT WE'VE REACHED.

I'M ASKING YOU FOR YOUR GUIDANCE
AND YOUR PROTECTION AS WE

JACK THIS ROOF SYSTEM DOWN.

AMEN.

[ APPLAUSE ]

♪♪

Narrator: IT TAKES TEAMS OF FIVE
WORKERS POSITIONED AT THE TOP

OF EACH 200-FOOT-HIGH TOWER
TO OPERATE THE JACKS.

♪♪

WELL, WE'VE GOT TO
STAY UP HERE UNTIL...

UNTIL IT'S DONE.

THAT COULD BE 15, 20 HOURS.

ONCE THIS COMES DOWN, THEY WILL
NOT BE ABLE TO PUT IT BACK UP,

SO IT'S CRITICAL
THAT YOU PAY ATTENTION,

IT'S CRITICAL THAT YOU KNOW
WHAT YOU'RE DOING,

AND IT'S CRITICAL THAT
YOU HAVE CLEAR COMMUNICATION.

ALL RIGHT, GUYS,
IT'S TIME TO GO.

LET'S START JACKING
THIS THING DOWN.

EVERYBODY MAKE SURE YOU GET YOUR
HANDS AND FEET OUT OF THE WAY.

PAY ATTENTION TO THE MOVEMENT.

Narrator: AVERY MUST COORDINATE
THE TEAMS AT THE TOP

OF EACH TOWER TO LOWER THEIR
JACKS AT EXACTLY THE SAME PACE.

WE JUST NEED TO MAINTAIN
GOOD COORDINATION

BETWEEN ALL THE TOWERS,
AND IT'S JUST A SLOW PROCESS.

SLOW AND STEADY.

Narrator:
AS THE TRUSSES DROP DOWN,

THESE PRECISION-ENGINEERED
BEARINGS THAT SLIDE

GENTLY TRANSFER THE ROOF'S
MASSIVE WEIGHT

FROM THE TEMPORARY TRUSSES

ON TO THE PERMANENT
CONCRETE COLUMNS.

THIS SLIDE BEARING IS DESIGNED
TO MOVE IN AND OUT

AS WE JACK THIS BUILDING DOWN.

IT'S GONNA ALLOW THIS TRUSS
TO MOVE AND FLEX.

Narrator: IT TAKES
EIGHT HOURS FOR THE TEAM

JUST TO REACH THE HALFWAY POINT
OF THE JACK-DOWN.

Martin: OKAY. COMING UP.

Narrator: BUT WITH
SEVEN INCHES STILL TO GO,

THEY RUN INTO TROUBLE.

BOY, WE'RE GETTING HEAVY.

YEAH, YOU'RE GETTING
HEAVIER, TOO.

Narrator:
THE JACKS ARE OVERLOADED,

AND THE HINGES
ARE CLOSE TO SNAPPING

UNDER THE ENORMOUS
WEIGHT OF THE TRUSSES.

Hatfield: SOME OF
THE IRONWORKERS UP ON THE TOP

OF THE TOWERS NOTICED THAT SOME
OF THE STEEL IS DEFORMING.

SO THEY HAVE STOPPED TO TAKE
A LOOK AT WHAT'S GOING ON.

Martin: YEAH, WE'RE GONNA
HAVE A LONG DAY.

Narrator: THE STEEL HINGES
ARE STARTING TO BEND.

IF THEY BEND EVEN A TINY
FRACTION OF AN INCH MORE,

THEY COULD BUCKLE.

THE WORST-CASE SCENARIO
IS THAT THE JACK WOULD FAIL

AND THE ROOF WOULD
COME DOWN VERY QUICKLY.

WE'RE NOT 100% SURE EXACTLY
WHAT'S GOING ON AT THE MOMENT.

THERE'S NO TELLING
WHAT COULD GO WRONG,

SO THAT'S WHY WE STOPPED
TO MAKE A PLAN TO FIX IT.

WE'VE GOT CREWS MOVING
AND GETTING READY

TO START REINFORCING
ON THE HINGES.

Narrator: THEY WILL TRY TO
STRENGTHEN THE HINGES

BY WELDING ON EXTRA-THICK
PLATES OF STEEL.

♪♪

EACH PLATE IS
CAREFULLY ENGINEERED

AND SENT UP TO THE TOP
OF THE TOWERS.

THE CREW WORKS 24/7 TO REINFORCE
ALL 64 HINGE ARMS

WITH THE INCH-THICK
STEEL ARMOR PLATES.

♪♪

THE NEXT DAY, THEY VERY
CAREFULLY RESTART THE JACK-DOWN.

Martin: EVERYTHING'S GOING TO BE
MONITORED AND WATCHED

AS WE BEGIN TO JACK
THIS ROOF DOWN AGAIN.

JUST ONE MORE STEP
IN THE PROCESS OF EATING THIS --

EATING THIS ANIMAL.
[ CHUCKLES ]

PAY ATTENTION TO THE MOVEMENT.

Narrator: THE TEAM KEEPS
A CLOSE EYE ON THE HINGES

TO MAKE SURE THEY HOLD UP.

WE JUST KEEP COMING DOWN
UNTIL WE SEE DAYLIGHT,

AND THEN THE TRUSS IS
HOLDING ITSELF.

Narrator: AFTER AN DIFFICULT
18 HOURS, TOUCHDOWN.

♪♪

Martin:
THE JACK-DOWN IS COMPLETE.

IT'S AWESOME.
IT'S AWESOME.

♪♪

YOU KNOW, THIS ROOF STRUCTURE IS
SO UNIQUE. IT'S AWESOME.

IT FEELS GREAT.

Narrator: WITH
THE ROOF TRUSSES NOW RESTING

ON THE CONCRETE COLUMNS
AROUND THE EDGE OF THE STADIUM,

THEY CAN TAKE DOWN
THE TEMPORARY TOWERS.

THIS CLEARS SPACE INSIDE
THE STADIUM BOWL

TO ERECT THE STANDS
FOR THE SEATS,

BUILD THE INTERIOR, AND INSTALL
THE RETRACTABLE ROOF PETALS.

Martin: MAJOR, MAJOR
ACCOMPLISHMENT.

NOW THE HARD WORK BEGINS.

♪♪

Narrator: OVER
THE NEXT FOUR MONTHS,

THE WORKERS PICK UP THE PACE.

THEY PIECE TOGETHER
THE GEOMETRIC STEEL

AND PLASTIC FACADE

TO CREATE THE STADIUM'S
DISTINCTIVE EXTERIOR.

♪♪

INSIDE, THEY INSTALL
1,100 TONS OF DUCTWORK

TO FEED
THE AIR CONDITIONING SYSTEM.

Martin: ATLANTA IS
A VERY HOT PLACE.

CAN'T IMAGINE SITTING
FOR THREE, FOUR HOURS

INSIDE A STADIUM
WITHOUT AIR CONDITIONING.

Narrator: THEY FEED IN 1,600
MILES OF ELECTRICAL WIRING

AND 60 MILES OF PIPES
TO SERVICE OVER 1,500 TOILETS.

WE'RE HERE IN THE MIDDLE
OF THE BOWL.

THERE'S FIVE MONTHS
UNTIL OPENING.

IT'S VERY EXCITING.

SO THE TOWERS ARE GONE NOW,
THE BOWL'S OPENED UP A LOT.

YOU CAN START TO FEEL
THE VOLUME OF THE SPACE.

IT'S A MUCH, MUCH
DIFFERENT ENVIRONMENT.

Narrator:
BUT THE STADIUM IS VAST.

SOME FANS WILL BE AROUND
300 FEET FROM THE FIELD

AND COULD STRUGGLE
TO SEE THE ACTION BELOW.

SO THE ENGINEERS' NEXT CHALLENGE

IS TO BUILD THE WORLD'S
BIGGEST SCOREBOARD.

INSTEAD OF A FLAT,
RECTANGULAR SCOREBOARD

THAT'S HARD TO SEE
FROM EVERY SEAT,

THEY'RE BREAKING
WITH TRADITION,

AND DEVELOPING
AN INGENIOUS SCOREBOARD

THAT CIRCLES 1,100 FEET

RIGHT AROUND THE OPENING
OF THE STADIUM ROOF.

IT WILL BE MADE UP OF 1,848
MASSIVE FLAT CABINETS

WITH FLAT SCREENS INSIDE,

EACH CAREFULLY ANGLED
TO CREATE THE CURVE.

CALLED A "HALO BOARD,"
THIS DESIGN SHOULD ALLOW FANS

TO SEE THIS
62,000-SQUARE-FOOT SCOREBOARD

FROM ANY SEAT IN THE HOUSE.

Hatfield: NOW THAT THE TOWERS
ARE UP, YOU CAN SEE

THE CURVATURE OF THE VIDEO HALO,

YOU CAN SEE THE STEEL TRUSSES
THAT SUPPORT THE VIDEO HALO.

SO THE SCALE OF THIS
IS JUST GIGANTIC.

IT'S THE BIGGEST
SCOREBOARD IN SPORTS.

Narrator: BUT THE SHEER SIZE
OF THE SCOREBOARD

CREATES A UNIQUE
PROBLEM FOR ERLEEN.

IF WE TRIED TO USE TRADITIONAL
FLAT SCREEN TECHNOLOGY

FOR THE HALO BOARD,
IT WOULD BE TWICE AS HEAVY

AS WHAT WE HAVE
DESIGNED FOR NOW.

Narrator: TO OVERCOME
THIS HEAVY-DUTY PROBLEM,

THE TEAM MUST RELY ON
BREAKTHROUGH TECHNOLOGY.

Narrator: AT ATLANTA'S
MERCEDES-BENZ STADIUM,

ENGINEERS ARE TRYING
TO BUILD A 1,100-FOOT-LONG

CIRCULAR SCOREBOARD FOR THE NEW
HOME OF THE ATLANTA FALCONS.

TO DEVELOP SOMETHING
LIGHTWEIGHT ENOUGH,

THEY TURN TO AN INNOVATIVE
FACTORY IN SOUTH DAKOTA.

HERE, TOBY PULSCHER PLANS
TO USE 37 MILLION

LIGHT-EMITTING DIODES, L.E.D.s,
WHICH WILL WEIGH ALMOST

50% LESS THAN STANDARD
FLAT-SCREEN LIGHT SOURCES.

ESSENTIALLY, YOUR IMAGINATION
IS THE ONLY THING

THAT LIMITS THE DESIGN
AND THE SIZE

AND THE SCOPE OF
L.E.D. DISPLAYS.

Narrator: EACH L.E.D.
HAS A FIXED COLOR --

RED, GREEN, OR BLUE.

BUT BY GROUPING THESE
THREE COLORS TOGETHER,

TOBY CREATES A PIXEL.

BY DRIVING THOSE L.E.D.s
AT DIFFERENT INTENSITIES,

MAKING THEM BRIGHTER OR DIMMER,

WE CAN EFFECTIVELY PRODUCE
ANY COLOR IMAGINABLE.

Narrator: 864 L.E.D.s
MAKE UP ONE 14x14-INCH PANEL.

23 PANELS ARE INSTALLED
INTO ONE HALO BOARD CABINET.

Pulscher: SO ONE OPTION IS THAT
WE COULD MAKE THE CABINETS

OUT OF STEEL,
BUT WEIGHT IS A BIG FACTOR,

AND STEEL IS A LOT HEAVIER
THAN ALUMINUM.

SO USING AN ALUMINUM CABINET
SAVES ON WEIGHT

AND SAVES ON SHIPPING COSTS
AND SAVES MONEY OVERALL.

BEFORE THE HALO BOARD
CAN BE SHIPPED TO ATLANTA,

THE PANELS ARE PUT THROUGH
RIGOROUS TESTING.

Gunnare: IT'S IMPORTANT
TO TEST OUR COMPONENTS,

THAT THEY'RE GOING
TO STAND UP TO THOSE

VAST TEMPERATURE CHANGES,
RAIN, SNOW.

'CAUSE WE DO NOT WANT THEM
BREAKING DOWN AT KEY MOMENTS

DURING THE BIG SHOW.

Narrator: VIBRATIONS CAUSED
BY THE SLIDING ROOF

COULD TAKE THEIR TOLL
ON THE SCREEN.

WHAT WE'RE DOING IS MAKING SURE
THAT THAT DISPLAY WILL BE ABLE

TO WITHSTAND THE OPENING
AND CLOSING OF THE ROOF.

Narrator: ONCE TESTED,
THE 1,848 CABINETS

WITH THE SCREENS INSIDE
NEED TO BE WRAPPED AND PACKED

FOR THE LONG TRIP SOUTH.

♪♪

BUT BEFORE THE TEAM IN ATLANTA
CAN INSTALL THE HALO BOARD,

THEY MUST FINISH THE COMPLEX
RETRACTABLE ROOF.

THEIR NEXT CHALLENGE
IS TO FIGURE OUT HOW TO

OPEN AND CLOSE THE ROOF
IN JUST 12 MINUTES.

Castle: WE'RE JUST GOING TO GO
STRAIGHT UP WITH IT.

I GET ASKED A LOT, "ARE YOU
REALLY GOING TO BE ABLE

TO DESIGN THAT? CAN THEY REALLY
BUILD SOMETHING LIKE THAT?"

Narrator: TO KEEP IT SIMPLE,
THE TEAM COULD MAKE THE ROOF

FROM TWO LARGE SECTIONS
THAT RUN ON LONG SETS OF RAILS,

BUT THESE ROOF PANELS
WOULD BE HEAVY

AND TAKE A LONG TIME
TO ROLL BACK.

SO ERLEEN'S ROOF IS DESIGNED
WITH EIGHT SMALLER PANELS

THAT RUN ALONG
16 SHORTER RAILS.

THE PANELS, CALLED PETALS,

ARE MADE UP OF FOUR
MASSIVE STEEL FRAMES.

EACH 450-TON PETAL
SITS ON TWO RAILS.

THE INNER RAIL IS JUST
LIKE ANY RAIL TRACK.

SETS OF WHEELS
ATTACHED TO THE PETAL

SHOULD ALLOW IT TO ROLL
SMOOTHLY ON TOP OF THE RAIL.

BUT THIS APPROACH WON'T WORK
FOR THE OUTER RAIL.

AS THE PETAL MOVES
OUT OVER THE BOWL,

THE BACK WOULD LIFT UPWARD

AND THE FRONT WOULD
TIP OVER AND CRASH.

SO THEY PLAN TO POSITION
THE REAR SET OF WHEELS

UNDERNEATH THE OUTER RAIL.

THIS LOCKS THE BACK OF THE PETAL
INTO THE STADIUM ROOF.

AS THE PETAL SLIDES
ALONG THE ROOF,

THE WHEELS ARE ENGINEERED
TO ROLL BENEATH THE OUTER RAIL

AND TO STOP THE PETAL
FROM FALLING.

Hatfield: BEING CREATIVE
IN STRUCTURAL ENGINEERING

IS WALKING A VERY FINE LINE.

WE HAVE TO FIGURE OUT EXACTLY
WHERE THAT FINE LINE IS.

Narrator: UP ON THE ROOF,
THE TEAM LAYS THE RAILS

THAT WILL HOLD THE PETALS.

GOOD. EVERYTHING'S TIED DOWN,
READY TO GO.

VERY NICE.

WHILE DOWN IN THE BOWL...

WE DON'T HAVE A SHIM
ON THIS SIDE.

...AVERY OVERSEES
THE CONSTRUCTION OF THE VAST

RETRACTABLE ROOF PETALS.

THE PETALS ARE TOO BIG
TO BE BUILT

AND LIFTED ON TO THE ROOF
IN ONE PIECE,

SO THEY ARE BUILT
IN FOUR SECTIONS,

A HEEL THAT CONNECTS
TO THE FIXED ROOF,

TWO MIDDLE PIECES, AND THE TIP
THAT SLIDES OUT OVER THE BOWL.

THE BOWL HAS BECOME
A MASSIVE FACTORY

CHURNING OUT PETAL SECTIONS.

OH, LORD. SPACE.

THERE'S NEVER ENOUGH SPACE.

AS WE BUILD THESE THINGS,
THESE PETALS,

IT'S CRUCIAL THAT EVERY LIFT

CONTINUES TO FOLLOW
THE NEXT ONE,

OTHERWISE, NUMBER ONE,
YOU CAN'T MEET THE SCHEDULE,

AND THAT'S WHAT THIS IS
ALL ABOUT, THE SCHEDULE.

Narrator: AVERY MUST
HIT HIS DEADLINE.

THE STADIUM HOSTS
ITS FIRST FALCONS GAME

IN LESS THAN FIVE MONTHS.

IT'S CRITICAL THAT
EVERY PIECE OF THE ROOF

IS PRECISELY THE RIGHT
SHAPE AND SIZE.

Martin: OH, MY GOD. WE'RE
CHECKING EVERY MEASUREMENT,

MAKING SURE
EVERYTHING'S LINED UP.

'CAUSE ONCE YOU GO UP
WITH IT UP IN THE AIR,

YOU'RE STUCK WITH IT FOR DAYS
WHILE YOU TRY TO GET IT FIT UP.

Man: THIS SIDE'S LOW.

YOU NEED TO COME DOWN 1/8.

Narrator: THE TEAM GEARS UP
TO LIFT ONE OF THE LARGEST

PETAL SECTIONS INTO PLACE.

Man: GOT TO COME UP 7/16.

EVERYTHING'S LOOKING
PRETTY GOOD.

Narrator: WITH A STORM
DUE TO HIT TONIGHT,

THEY NEED TO GET MOVING,
AND FAST.

THE WEATHER HAS AFFECTED
THE SCHEDULE

TREMENDOUSLY ON THIS PROJECT.

JUST TWO WEEKS AGO,
WE HAD FOUR DAYS OF DOWN TIME,

JUST STRICTLY FOR RAIN.

WHEN WEATHER COMES IN,
IT SHUTS YOU DOWN.

INSTALL 71,000 SEATS.

END-TO-END.

THAT'S 23 MILES OF CHAIRS.

EACH CHAIR MUST
BE INSTALLED BY HAND.

LET'S GO.

IT'S QUICK. THIS IS ONE OF THE
FASTEST SYSTEMS IN THE WORLD.

YOU'VE GOT TO BE FIT,
YOU'VE GOT TO HAVE GOOD CARDIO,

YOU NEED EVERYONE TO COME
AND GIVE IT WHAT THEY'VE GOT.

Narrator: ADAM'S HUMAN CHAIN
CAN INSTALL 40 SEATS PER MINUTE.

WE USED TO CARRY 'EM UP, BUT
PEOPLE'S CARDIO WOULD BURN OUT.

THERE WE GO.

NOW I FEEL IT.

Narrator: THE CHAIRS ATTACH
TO AN ALUMINUM BEAM

SET INTO THE CONCRETE BOWL.

AFTER THE BEAM'S ALL INSTALLED,

THE CHAIR JUST
KIND OF SLIDES IN.

THIS IS A UNIQUE SYSTEM
BECAUSE IT CLIPS INTO THE BEAMS.

Narrator: BY MORNING, THE CREW
HAS INSTALLED ALMOST

1,000 SEATS, WHICH THEY'VE HAD
TO COVER WITH FIRE BLANKETS.

THERE'S STILL AN INCREDIBLE
AMOUNT OF WORK

GOING UP ON THE ROOF.

THERE'S STUFF DROPPING IN,

SO THEY'RE TRYING TO PROTECT
THEM THE BEST THEY CAN

SO THEY DON'T GET CHIPPED,
BROKE, STAINED, MELTED.

Narrator:
1,000 SEATS DOWN, 58,000 TO GO.

Engel: WE'RE UNDER
A LITTLE BIT OF COMPRESSION

HERE AT THE STADIUM, SO IT'S
GOING TO BE EXHILARATING,

Narrator: THE TEAM BUILDING
THE NEW MERCEDES-BENZ STADIUM

FOR THE ATLANTA FALCONS
HAS REACHED THE FINAL STAGE.

OVER THE LAST THREE MONTHS,
THEY'VE COMPLETED THE EXTERIOR

AND BUILT THE STEEL FRAMES
OF THE EIGHT VAST

RETRACTABLE ROOF PETALS.

INSIDE, THE SEATING
IS ALMOST FINISHED.

NOW THEY CAN BEGIN TO
INSTALL THE WORLD'S

BIGGEST SPORTS SCREEN...

...THE 60-FOOT-HIGH,
1,100-FOOT-LONG HALO BOARD.

IT'S AMAZING HOW BIG IT IS
AND HOW MUCH WEIGHT IT IS.

Narrator: WITH THE L.E.D.
SCREEN CABINETS NOW ON SITE,

THE TEAM MUST BOLT THEM TOGETHER
IN 14-FOOT-HIGH BLOCKS.

NO DOUBT, WE'VE GOT TO GO FULL
SPEED AHEAD, MAKE OUR DEADLINE.

Narrator: INSTALLING THE 616
SECTIONS OF THE SCREEN

WILL TAKE GREAT SKILL.

WE HAVE A CREW OF ABOUT 15 GUYS,

SO WHEN A SECTION
COMES TO THEM,

THEY'LL GRAB IT, SET IT
IN PLACE VERY CAREFULLY,

AND THEN THEY'LL
BOLT THEM TOGETHER.

AND ONCE THEY GET IT
ALL ALIGNED,

WE'LL GET IT WELDED IN PLACE.

♪♪

ON THE FACE OF IT, OF COURSE,
YOU HAVE THE L.E.D.s,

SO THEY CAN GET DAMAGED
VERY QUICKLY

IF YOU'RE NOT VERY CAREFUL.

Narrator: AS THE 3,500-TON
RETRACTABLE ROOF CLOSES,

THE STEEL HOLDING THE HALO BOARD
WILL MOVE AND FLEX,

PUTTING L.E.D. SCREENS AT RISK
OF BEING CRUSHED TOGETHER,

WHICH WOULD DAMAGE THE BOARD.

[ GLASS SHATTERS ]

SO THE TEAM HAS ENGINEERED
EIGHT INGENIOUS EXPANSION JOINTS

INTO THE HALO BOARD STRUCTURE.

AS THE ROOF SLIDES AND THE STEEL
HOLDING THE HALO BOARD BENDS,

THE JOINTS SHOULD ABSORB
THE MOVEMENT,

PROTECTING THE VAST SCREEN.

THIS TEAM MUST BOLT
30 SCREEN SECTIONS

INTO PLACE EACH DAY
TO STAY ON TRACK.

Martin: WE'RE EXPECTING TO SEE
THE FANS IN HERE REAL SOON.

NEXT THING YOU KNOW, YOU'LL HAVE

Narrator: BUT THE TEAM FACES
ONE FINAL CHALLENGE

BEFORE FINISHING
THIS INSTALLATION.

THEY MUST ATTEMPT
TO CLOSE THE WORLD'S

MOST COMPLEX RETRACTABLE ROOF
FOR THE VERY FIRST TIME.

THIS IS A CRUCIAL TEST,

THE MOMENT THAT EVERYBODY
HAS BEEN WORKING TOWARDS

OVER THE PAST THREE YEARS.

IT'S A BIG MOMENT.
IT'S A BIG MOMENT.

EVERYBODY'S EXCITED, READY
TO GET THIS THING CLOSED UP.

PEOPLE, LIKE, ASK ME,
"CAN YOU REALLY DO THAT?

ARE YOU CRAZY?

CAN YOU GET THIS THING TO WORK?"

WE DON'T WANT
ANY MECHANICAL FAILURES.

IT IS VERY IMPORTANT THAT
THIS TEST GOES WELL.

Narrator: TO WORK,
ALL THE PETALS MUST

ROLL ALONG THEIR TRACKS
TOGETHER AT THE RIGHT SPEED.

IF ANY OF THE PETALS
RUN AT THE WRONG SPEED

OR HAVE BEEN INSTALLED
AT THE WRONG ANGLE,

THE FRAMES COULD COLLIDE,
JAMMING THE ENTIRE SYSTEM.

TODAY, WE'RE CLOSING THE PETALS
FOR THE FIRST TIME.

THIS MOVE IS PROBABLY THE MOST
IMPORTANT MOVE THAT WILL HAPPEN

IN THE LIFE OF THIS STRUCTURE.

ALL EIGHT PETALS
WILL MOVE SIMULTANEOUSLY.

THEY HAVE TO MOVE REAL
CLOSE TOGETHER AT ALL TIMES,

BECAUSE AT ANY MOMENT,
THEY HAVE TO BE WITHIN A FOOT

OR TWO FEET OF EACH OTHER,

OR ELSE THEY'LL
RUN INTO EACH OTHER.

SO WE HAVE TO BE VERY CAREFUL.

Narrator: ANDREW COMMANDS

Narrator: 96 MOTORS
POWER THE WHEELS

ON THE PETALS' INNER RAILS,

GRADUALLY DRIVING THE EIGHT
VAST STEEL ROOF SECTIONS.

FOR OPENING DAY,

THE ROOF MECHANIZATION
WILL BE COMPUTERIZED.

BUT FOR THIS TEST, THEY ARE
DOING EVERYTHING MANUALLY.

TO USE TAPE MEASURES.

WE DON'T NECESSARILY KNOW WHERE
ALL THE PETALS ARE AT ONCE.

91 1/4%.

91 1/2%.

WE'LL STOP AT ANY
BIG POP OR BANG

OR ANYTHING OUT OF THE ORDINARY.

AND WE'LL SOUND AN ALARM.
